I feel random

As a lab aide, I learned:

• How to pour stuff without spilling
• How to set things on fire without Mrs. Jones noticing safely
• That iron filings are really cool in a glass plate on a magnetic stirrer
• That Mrs. Jones' sink can make a real big mess sometimes
• That acetone is flammable
• That it's not a good idea to be playing with a lighter while the other lab aide is using acetone to help scrape a label off of a bottle
• That bending an orange-hot glass stirring rod into the first letter of your first name is really cool
• To make sure that the cap on the bottle of conc. HCl is really tight before tilting it over to put in the acid cabinet
• That hydrogen effuses out of latex gloves overnight
• That filling up a latex glove with the gaseous product of a Zn and HCl reaction and lighting it can make the glove jump a few feet in the air
• That the plastic grating at the bottom of the sink is, in fact, plastic, and can therefore melt
• That pouring too much water into the lab sinks can make it leak into the classroom below
• That the zinc pyrotechnic demonstration looks totally awesome but is a mess to clean up
• That a screwdriver and a little knowledge can increase the flow rate tenfold of a bic lighter
• To never leave a latex glove filled with colored water near Chris Simpson
• Lots more that will come to me later.
